Cells

Front 1

nucleus

Back 1

contains the cell's DNA and with it the coded instructions for making proteins and other important molecules

Front 2

vacuole

Back 2

saclike structures that store materials such as water, salts, proteins, and carbohydrates, in plants they mostly store water and affect the turgor pressure of the plant

Front 3

mitochondria

Back 3

convert oxygen and chemical energy stored in foods (ex: glucose) into energy for cells to use through a process called cellular respiration

Front 4

chloroplasts

Back 4

capture energy from the sunlight and convert it into chemical energy in a process called photosynthesis

Front 5

cytoplasm

Back 5

material that fills the cell and holds the organelles

Front 6

cell membrane

Back 6

semi permeable layer of cells that controls diffusion in and out of the cell

Front 7

cell wall

Back 7

only in plant cells, rigid outer layer made of cellulose and gives cells and plants structure

Front 8

Robert Hooke

Back 8

first scientist to view cells under a microscope

Front 9

Schleiden and Schwann

Back 9

published Cell Theory

Front 10

cell theory

Back 10

1. all living things are made of cells

2. the cell is the basic unit of life

3. living things come only from other living things

Front 11

Watson and Crick

Back 11

developed the first 3 dimensional model of DNA showing the double helix shape

Front 12

Rosalind Franklin

Back 12

took excellent xray photographs of DNA

Front 13

permeable

Back 13

allows entry

Front 14

impermeable

Back 14

does not allow entry

Front 15

semi-permeable

Back 15

allows passage of certain molecules but prevents passage of other molecules

Front 16

plasmolysis

Back 16

when a cell loses too much water and shrivels
